GA50 Embedded Sensing Element
The GA50 is a high performance open loop SiMEMS analogue output accelerometer available in various sensing ranges...
Standard ranges are 5g & 40g with custom solutions available in volume. The GA50 delivers unparalleled performance, capable of low residual noise <2 μg / √ Hz (VRW) and low short-term bias <100μg. The accelerometer is based on a bulk micro-machined silicon MEMS device and an ASIC with an analogue front end (AFE) and temperature sensor, assembled in a compact hermetically sealed LCC20 package.
Designed for integrated volume applications and PCB designs.

JA-40GA Servo-Balanced Quartz Accelerometers
The JA-40GA is a high performance servo balanced quartz accelerometer for measuring very low levels of vibration. Servo balanced technology is class leading in terms of stability over temperature over time, essentially zero drift. The JA-40GA is available in ranges 2, 4 & 8g with residual noise 0.1 x 10-6 G/√ Hz max and Frequency response 200 Hz.
What is it used for?
Designed for moderate volume applications, some integration required.
The JA-40GA accelerometer is therefore ideal for use in structural health monitoring, active vibration control systems, and earthquake observation, where even the slightest tremors can be indicative of catastrophe.
Features
- Ultra-low noise
- Excellent thermal stability
- Low frequency operation
- -20°C to +70°C operating temperature
- Easy to install
EQ Series MEMs Capacitive Accelerometer
The Accelerometer EQ-series are based on proven MEMS technology and capacitive operating principle. The integrated electronic circuitry enables a differential analog voltage output (± 2.7 V FSO) and flexible power supply voltage from 5 to 40 VDC.
The sensors of the ASC EQ series feature an ultra-low noise level and achieve are solution of less than 1μg. They therefore fulfil the requirements of motion class B of seismic measurements.
The sensor ASC EQ-x211 feature alight weight aluminium housing and the sensors ASC EQ-x215 provide a robust stainless-steel housing, both with protection class IP65 and with detachable cable aswell as configurable length and connectors. The accelerometers are available in uniaxial, biaxial and triaxial configuration.
Designed for Test & Measurement applications, plug & play.

KB12VD & KS48C IEPE Seismic Accelerometers
The KB12VD and KS48C are specifically designed IEPE Seismic Accelerometer for Vibration measurements and building vibrations, particularly at low frequencies not exceeding 0.6g.
The extremely sensitive piezo technology provides excellent resolution and lowest noise. KB12VD has a particularly highly sensitivity to mass ratio and features air damping for resonance attenuation and overload protection by friction coupling. KS48C is designed specifically with IP67 environment protection in mind. Sensitivity of 10000 mV/g to a maximum of 0.6g, ultra low noise 2 μg/√Hz @ 0.1Hz down to 0.1 μg/√Hz @ 10 Hz.
Designed for Test & Measurement applications, plug & play.
